Initiating a chat

Select the contact and then select Start Chat option. You will be requested to enter your PIN number to launch a chain of encryption processes. You need to enter PIN every time you start a chat, call or send a file via No.1 BC: Live.

Why enter PIN

Every time for every communication session No.1 BC: Live generates new keys. PIN number serves as an authenticator to verify if the user really is the card owner and really has an intention to encrypt some information.

Initiating a chat

System on-card-generated pair of asymmetric keys is used to encrypt and transmit one-time random encryption key.

Public key is sent to another user to encrypt data. Public key may be sent to as many users as you need. Private key (used only for decryption) always stays locked on-card and is never copied outside of the card. Each No.1 BC: Live user has own unique pair of keys. Unique private key is always kept secret and protected with PIN.

Connecting

Chat invite

Enter PIN

When PIN is confirmed the System generates one-time random key, which will encrypt only this particular conversation.

Random one-time key

Each new chat conversation, voice call or file transfer session will have own one-time randomly generated symmetric key.

Encrypting conversation key

User, who aceepted the chat invite uses chat initiator’s public key and encrypts the session key. Encrypted package is sent back to chat initiator.

Decrypting response

Chat initiator gets encrypted package as a response to start a chat. Using the private key locked on-card the System decrypts session key, which will be used only for this particular conversation.
